I am using LPTIM for periodic ADC reading (every ~250ms) and periodic IWDG refresh. CPU should go to Stop mode when the ADC value is under certain value. If the ADC value is over certain value then CPU should reset end continue in Run mode. ADC is cl...
I am working in a project where I have to sample a signal with a sampling frequency of 8 kHz with the ADC. That data is send from the ADC to SRAM using DMA and then send through UART interface. I am using a "Blue pill" board (STM32F103C8T6) with a sy...
They don't make DRAM QSPI chips in an SO-8 package with more than 64 Mbits (maps to 2 Mbytes * 32). Given the current processor shortage, I've got an application where I'd like more memory (and I'm using a 100 pin package which is quite pin limited,...
The errata sheet of the STM32F042 states:The time-triggered communication mode described in the reference manual is not supported. As a result, timestamp values are not available. The TTCM bit of the CAN_MCR register must be kept cleared (time-trigge...
Hello I'm using SPI to interface my STM32F7 with the SX1262 radio. I got a weird behavior, I'm using a GPIO to toggle the NSS pin. But sometimes it toggles randomly during the data transfer. You can see on the following screenshot of my logic analyze...
I would like to know what load capacitance to have the Processor and RTC crystalsmade by the vendor. Typically the crystals are precision ground with a load capacitance such that when operating in the circuit the frequency will be very close to what...
My idea was simple. Set TIM to have 1MHz after prescaler. Then set ARR to the number of microseconds. So - I toggle GPIO pin each period elapsed and I can measure the time on oscilloscope.And here come troubles: for set 1us i get 2us. For 2us I get 2...
I am using Segger Embedded Studio 6.32 to develop a project for the STM32L062K8U6. While there are some start-up files created by the SES project wizard, I am not using any pre-built libraries and developing all my own code based on information from...
Hello, I made a an esc using an arduino a year ago and I wanted to try it with my stm32L476RG, for some reason my code doesn't seem to work, and I think that I'm doing the switching of the comparator input minus wrong, can you tell me if this is the ...
